Definitions
- the present invention relates to finish compositions for use with synthetic filaments and relates more particularly to a neat oil finish composition and synthetic filaments coated with such composition.
- Known neat oil finishes typically used for polyamide and polyester yarns contain high percentages of nonionic surfactants, e.g., 30 weight percent, which provide good dissipation of electrostatic charge, filament bundle cohesion, and desirable wetting properties to the yarn.
- nonionic surfactants e.g., 30 weight percent
- nonionic surfactants increase the propensity of the finish to undergo oxidative degradation and to fume when exposed to heat. The disadvantages become particularly apparent when such finishes are used as "spin finishes" in the manufacture of high tenacity polyamide and polyester industrial yarns where high draw ratios and high temperatures are used.
- nonionic surfactants in neat oil finishes can also cause problems when a yarn is to be used in woven fabrics.
- Nonionic surfactants are sometime incompatible with size, especially polyacrylic acid size, and thus nonionic surfactant can cause sizing, weaving, and scouring problems for fabric makers.
- the invention provides a lubricating finish composition and synthetic filaments coated with the composition.
- the composition of the invention comprises: about 80 to about 99 weight percent lubricant; and about 1 to about 20 weight percent alkali metal salt of a branched or unbranched aliphatic monocarboxylic acid having at least 8 carbon atoms.
- the finish composition is a liquid at a temperature below about 150 °C.
- the lubricant preferably is selected from the class consisting of natural and synthetic esters and natural and synthetic hydrocarbons having a number average molecular weight of at least about 550 atomic mass units (amu) and having an iodine value of less than about 15.
- the finish composition is substantially free of nonionic surfactants.
- the branched or unbranched aliphatic monocarboxylic acid of the salt has at least about 14 carbon atoms.
- the lubricating finish is advantageously used as a neat oil finish for synthetic filaments including polyamide and polyester multifilament yarns and is particularly useful as a "spin finish' 1 for industrial yarns.
- the finish of the invention provides- electrostatic protection while avoiding the high viscosity problems associated with the use of high percentages of nonionic surfactants.
- preferred finish compositions which contain optional stabilizers provide dramatically improved thermal-oxidative stability as measured in an oven varnish test.
- the preferred finish compositions also exhibit low fuming.
- the finish compositions can easily be made compatible with polyacrylic acid size when the yarns are to be used in woven fabrics.
- the finish composition includes about 80 to about 99 weight percent lubricant, preferably about 85 to about 98 weight percent lubricant.
- the lubricant should be a lubricant or mixture of lubricants suitable for use in a neat oil finish and thus should not fume excessively on hot machine parts during spinning of yarns or in subsequent end-use processing.
- the lubricant is selected from the class consisting of natural and synthetic esters and natural and synthetic hydrocarbons having a number average molecular weight of at least about 550 amu.
- the lubricant used can be a liquid at or below room temperature for ease of handling and consistent end-use performance even at low temperatures. However, for some end-use applications, solid lubricants that melt at or above room temperature may be desirable. In any event, the melting point of the lubricant must not be too high since it is necessary for the finish composition to be a liquid at a temperature below about 150 °C in order for the composition to be an effective neat oil finish. For resistance to oxidative degradation, especially varnishing during high temperature processing, the lubricant should be low in unsaturation. Preferably, unsaturation as measured by iodine value is less than about 15.
- suitable natural and synthetic ester lubricants include mono-, di-, and polyesters such as pentaerythritol tetrapelargonate, coconut oil, neopentyl glycol diisostearate, and stearyl stearate.
- suitable natural and synthetic hydrocarbons are mineral oil and poly ⁇ — olefins, e.g., hydrogenated decene tetramer.
- the finish composition also includes about 1 to about 20 weight percent of alkali metal salt of a branched or unbranched aliphatic monocarboxylic acid having at least 8 carbon atoms, preferably at least 14 carbon atoms.
- alkali metal salt of a branched or unbranched aliphatic monocarboxylic acid having at least 8 carbon atoms will hereinafter be referred to as "soap".
- the composition includes about 2 to about 15 weight percent soap.
- the soap can be provided by a single soap or can be a mixture such as the soaps which result when the monocarboxylic acid used to make the soap is from a natural source or a fraction thereof.
- the soap can also be a tailored mixture adapted for a particular end use.
- soaps in the composition which make the composition a liquid at a temperature below about 150 °C so that the composition will be a liquid at the temperature of application to a filament.
- Temperatures of application of neat oil finish can range from about 25°C to 150°C with preferred temperatures of application being from about 50°C to about 100°C.
- the finish composition is a liquid at a temperature below about 100 °C.
- a wide variety of soaps are useful in accordance with the invention, for example, potassium stearate, potassium isostearate, sodium stearate and sodium isostearate.
- some soaps may be difficult to use, particularly depending on the alkali metal hydroxide used to make them, since the soaps may cause gelation of the compositions. Soaps which are potassium salts and mixtures of potassium salts with other alkali metal salts are preferred .
- Soap in the finish serves as a surfactant and antistat and thus it dissipates accumulated electrostatic charges on the yarn threadline during yarn manufacturing and end-use processing.
- the soap can be added to and mixed with other finish components to provide the finish composition or preferably is made in situ by adding the alkali metal hydroxide to stirred monocarboxylic acids mixed together with one or more of the other finish components, i.e., lubricant, nonionic surfactant (if present) and stabilizer (if present).
- lubricant i.e., nonionic surfactant (if present) and stabilizer (if present).
- all, or the remaining portion of the lubricant can then be added and mixed to form the finish composition.
- the alkali metal hydroxide should be dissolved in water to facilitate the neutralization reaction.
- the concentration of the alkali metal hydroxide should be sufficiently high that the amount of water remaining in the finish is not high enough to cause phase separation in the resulting finish.
- excess water could be removed after neutralization to improve finish homogeneity.
- a suitable concentration of alkali metal hydroxide to avoid having to remove water is in the range of about 45-55% by weight.
- alkali metal hydroxides When two alkali metal hydroxides are used to form the soap, they can be added together or in sequence as may be desired.
- Finish compositions in accordance with the invention may incorporate soaps which are completely neutralized or which contain excess monocarboxylic acid or excess alkali metal hydroxide.
- soaps which are completely neutralized or which contain excess monocarboxylic acid or excess alkali metal hydroxide.
- the desired soap can conveniently be prepared by adjusting the proportions of the monocarboxylic acid and the alkali metal hydroxide.
- finish compositions may optionally contain nonionic surfactants in an amount not more than- bout 5 weight percent for the purpose of improving end use performance.
- the amount of nonionic surfactant must be greater than 0.1 percent to have any significant effect.
- examples of possible nonionic surfactants are ethoxylated carboxylic acids and ethoxylated alcohols.
- nonionic surfactants are present in sufficient quantity, they can be a suitable reaction medium for in situ soap preparation and little or no lubricant need be added until the soap has been formed.
- the finish composition preferably comprises a stabilizer in the amount of about 0.05 to 5 weight percent to provide additional thermal-oxidative stability.
- the stabilizer can be a single compound such as an antioxidant or can be a stabilizer package containing an antioxidant together with additional materials for the purpose of enhancing oxidative stability. Provided that they enhance finish properties, any of a wide variety of stabilizers known for use in finishes can be used in a finish in accordance with the present invention.
- An example of a stabilizer advantageously used in accordance with the present invention is a stabilizer package of trilaural phosphite and polydimethyl siloxane.
- the finish composition is used as a neat oil to coat synthetic filaments, i.e., the finish composition contains less than about 5 weight percent water when applied.
- the finish is preferably used with filaments of a polymer selected from the class consisting of polyamide homopolymers and copolymers and polyester homopolymers and copolymers. While the finish has a number of potentially beneficial applications, the finish is well suited for use as "spin finish" when applied to an as-spun multifilament yarn which is subsequently drawn, particularly when high draw ratios and high temperatures are employed.
- the finish may be applied by any of a variety of known methods for applying neat oil finishes such as using a rotating roll or metering tip applicator.
- the finish composition is preferably applied at a temperature of about 25°C to about 150°C, most preferably, about 50°C to about 100°C. Preferably, the amount of finish applied is about 0.2 to about 2.0 weight percent.
- TEST METHODS Iodine Value (AOCS Method Cd 1-25) is determined by the Wijs method and expressed as the number of centigrams of iodine absorbed per gram of lubricant.
- Viscosity is measured with a viscometer sold under the trademark BROOKFIELD® SYNCHRO-LECTRIC by Brookfield Engineering Laboratories, Inc., Stoughton, Massachusetts. pH is measured as a 5 weight percent dispersion in demineralized water using a pH meter.
- test finish(es) and control finish(es) are prepared by precisely weighing 0.30 - 0.35 grams of finish into previously weighed 57 mm aluminum weigh dishes. These dishes are randomly placed into 16" x 9" x 2" (41 cm x 23 cm x 5 cm) porcelain coated steel trays and placed in an electrically heated forced air oven. After heating at 225 °C for 16 hours, the trays are removed and allowed to cool to room temperature before re-weighing the aluminum weigh dishes with finish residue.. Then 10 - 20 grams of acetone are added to the weigh dishes to remove soluble residue.
- the acetone is poured out of the weigh dish and any remaining acetone soluble residue is removed by rinsing with a stream of acetone from a squeeze bottle.
- the aluminum dishes are dried about 10 minutes in a 75°C oven and cooled to room temperature before a final weighing of aluminum dishes to determine the percentage of acetone-insoluble varnish based on the original sample weight.
- Size Kick-Out Test Three grams of finish are added to a beaker containing a stirred solution of 5 grams of polyacrylic acid active size in 95 grams of water. After 5 minutes, stirring is stopped. After standing for one day, if a sticky film of size forms on the surface of or a sticky precipitate forms on the bottom of the size solution, the finish fails the size kick-out test.
- Example finishes A and B with the compositions listed in Table 1 are prepared by charging a vessel with all the components except the pentaerythritol tetrapelargonate lubricant and the potassium hydroxide (KOH). With mechanical stirring, the KOH is added as a 45% water solution to form the potassium isostearate soap in situ. The stirring is continued for an additional 10 minutes after the addition is complete to assure complete reaction. The pentaerythritol tetrapelargonate lubricant is then added slowly with stirring to complete the preparation of the neat oil finish.
- KOH potassium hydroxide
- Example finishes C and D with the components listed in Table 1 are prepared similarly. However, since these finishes contain no nonionic surfactant, a part of the pentaerythritol tetrapelargonate lubricant (equal to the isostearic acid weight) is added prior to the neutralization step which forms the soap in situ.
- the finishes are subjected to a number of test procedures to predict performance in use and the results are reported in Table 2.
- the Comparative finish is a neat oil finish of the type which is used commercially and has the following composition:
- Finish D is used as a spin finish for making a 1260 denier, ⁇ 9.8 gpd tenacity, 66 nylon industrial yarn using the process described in U.S. Patent No. 3,311,691.
- the finish is applied at a temperature of about 80°C in the amount of about 1.0% by weight. Good spinning performance, i.e., no adverse effect'on spinning breaks or broken filaments, is observed.
